Hi
Im about to change my turbo next week (Golf MK4 PD150 )...but just double checking all vac lines before i fork out for a new turbo .
I have checked all lines and everything is fine but if i put a vac gauge on the pipe coming off the servo pipe to n75 valve etc ...what sort of vac should i have (psi or bar )
I have an old vac gauge which does plus and minus psi i think ( like a turbo boost gauge ) and would like to check that there is enough vacuum in the system .
Any help most appreciated
Karl
